Mon-Day 2
Bio - we discussed the various sources/causes of disease/failure to maintain homeostasis, focusing on the general/nonspecific forms of protection: skin, mucus, stomach acid, tears, saliva, and cilia.
AP Chem - we discussed collision theory as it relates to the factors that cause an effective collision. We related the temperature of a reaction mixture to the fraction of "molecules" that have SUFFICIENT (kinetic) energy to MEET or EXCEED the activation energy (Eact) requirement for bond breakage; this is one of the TWO factors required for an EFFECTIVE collision i.e. a reaction.
We then discussed the Arrhenius equation, which was derived from the factors in the previous discussion.
We showed how kinetics data on rate constants at various temperatures for a given reaction can be used to determine the activation energy for a given reaction as well as the, "A term", the frequency factor, which is a constant for a given reaction (this constant is the same no matter what the temperature).
